oh yeah. i've mapped it starting at address 0x3000 but the hardware maps the ROM chip in starting at 0x0100, where it just gets aliased all the way up to 0xFFFF. the absolute jump addresses located in the vectors at the top of the ROM refer to addresses starting at 0x3000, so i'm just using that.
hmm, looks like there are a few instructions that aren't 6502. apparently Rockwell defined a few new ones. it would be nice if Ghidra could handle those.
